產品介紹

Description

This thermocouple-to-CAN module produces temperature data from 4 thermocouple sensors and outputs it via CAN bus. The module is 100% standalone - no PC required.

The module supports all thermocouple types (B, E, J, K, N, R, S, T) and can be daisy-chained for 8, 12, 16, ... channels.

You can integrate the module with any CAN bus system - e.g. to provide temperature data for your ECUs or existing CAN hardware.

As an example, you can use the module as an add-on for the CANedge - ideal for e.g. engine dynos, EGT analysis, HVAC monitoring and other temperature telematics use cases.

Probes not included - see suggested suppliers. Optional adapters (dropdown).

Add temperature data to your CAN bus

Need to inject temperature data directly into your CAN bus?

The thermocouple-to-CAN module can be used standalone to inject CAN frames with temperature into your CAN bus system. The data can be consumed by other CAN nodes on the network - e.g. ECUs, cabin displays, CAN loggers or telematics control units (TCU). To ensure compatibility, you can modify the module output bit rate and CAN IDs via the simple config editor. Ideal for use in e.g. automotive development, engine dynos, fleet management, dispute handling and more.

CAN + temperature data logging & telematics

Need to collect vehicle CAN bus and temperature data via SD/WiFi?

The CANmod.temp can be deployed as an 'add-on' module for the CANedge. Simply configure the CANedge to provide a 5V power out via the 2nd port - and connect the CANmod.temp via the optional adapter cable. This lets you log e.g. vehicle CAN bus data via channel 1 and time-synced temperature data via channel 2. This provides a flexible data logger for exhaust gas temperature (EGT) analysis - or a telematics solution for automotive heating, ventilation, and air conditioning (HVAC) applications.

On-road vehicle temperature telematics

Need to collect vehicle and temperature data via 3G/4G?

The CANedge2 can upload data while on-the-road using e.g. a 3G/4G USB router. You can power the 3G/4G hotspot from the vehicle - or use our DB9-DB9/USB adapter to power both the hotspot and CANmod.temp via the 2nd port of the CANedge2. The uploaded log files can e.g. be visualized in telematics dashboards. Ideal for e.g. 'temperature telematics' use cases like HVAC monitoring, refrigirator tracking for perishable goods, temperature-based alerts, predictive maintenance and more.

Daisy Chain Thermocouple to CAN bus temperature sensor modules
 

Daisy-chaining thermocouple modules

Need a larger number of thermocouple channels?

The CANmod.temp is extremely simple to setup and configure. With all data contained in 1 CAN frame, you can quickly daisy-chain several modules to add 8, 12, 16, 20, 24, 30, ... thermocouple channels to your CAN bus (e.g. using DB9-Y-splitters). Every individual thermocouple probes can be independently configured to any type - allowing for complete customization. If you wish to record the data to a CAN bus data logger, you can use the CANedge to easily power a full chain of modules via the 2nd port.
